When you just over-exaggerate a
pelvic thrust in a very upwards motion. It’s as if your
boner is just laying upright on your stomach, trying to pound some angel’s pussy.
“This one stripper at the club was so into me. I was pimp thrusting her for half the night cuz she was just towering over me”
The male equivalent of a queef, a dick fart. It's also a medical condition and you should get that checked out.
"If you shweef, there might be something wrong with you."
"Dude my dick just farted, I've never shweefed before."
